Social spaces
From Destiny 2 Wiki
General Information
Replacing The Tower from Destiny 1 is The Farm, one of the locations that serve as the social hub area where players congregate. Players can find various quests and vendors while in The Farm. It is a place where players can socialize with friends or mingle with strangers. They can purchase new weapons and armor and compare them with others.
However later within Destiny 2 the player will unlock a new and improved Tower which includes all of The Farm's contents.
